Which one of the following statements best describes the solution produced when an Arrhenius acid is dissolved in water? A) The only positive ion in solution is H . B) The only positive ion in solution is NH . C) The only negative ion in solution is OH . D) The only negative ion in solution is HCO .

Option (A) is the correct answer.

Explanation:

Arrhenius acids are the species which dissociate to give hydrogen ions, that is, .

For example,

In the given example, HCN is donating the hydrogen ion therefore, it is an acid whereas is accepting the hydrogen ions so it acts as a base.

Whereas according to Arrhenius, bases are the species which dissociate to give hydroxide ions, that is, .  

For example,

Thus, we can conclude that the statement only positive ion in solution is best describes the solution produced when an Arrhenius acid is dissolved in water.

for points guys

the answer would be a
